Get a mask with a specific number of voxels randomly distributed on the input image/mask
1 | randomMask(img, nsamples, perLabel = FALSE, seed)
|
img |
an antsImage, either continuous or mask-like. This will define the space where to sample voxels from. If this image is continous (i.e., a T1), voxels will be sampled from all nonzero voxels. |
nsamples |
the number of random voxels to select from |
perLabel |
logical, if true the input image must be multi-label and the the output will have nsamples from each label (i.e., 200 samples from each label) |
seed |
random seed |
binary antsImage with random voxels set to 1
